  • Baron Services Powers Weather App with MapQuest for Business

    Baron Services, Inc.Do you remember that last weather alert you received on your mobile phone? There's a good chance it came from Baron Services' weather app, powered by MapQuest for Business. If you're one of the millions of users of local television stations' private-labeled weather apps powered by Baron, MapQuest for Business helps to determine if you're in the path of severe weather.

    It's all about the weather

    Huntsville Alabama-based Baron Services is a leader in weather intelligence data. Baron partners with a wide array of customers spanning from television to the U.S. military and foreign governments. At any given time, thousands of general aviation pilots even depend on Baron for weather data needed to circumvent potentially dangerous flight conditions.

    A critical need for location accuracy

    Due to issues with reliability and accuracy with Baron's previous provider, Baron looked to replace its geocoding APIs in 2012. Since severe weather can be extremely isolated to a very small geographic area, location accuracy is of utmost importance. People at risk of being in the direct path of hazardous weather need ample warning, while those outside the path don't need false alarms that might cause them to question forecast accuracy. Baron Services' Software Department Manager, Sherman Wilcox, reflects on the importance of geocoding accuracy in their apps, "Whether it's a tornado warning, flash flood, lightning or other severe weather, when we send out an alert it's extremely important that the people in the path of that weather get notified. That's where location accuracy is critical." 

    Powered by MapQuest for Business

    After an extensive search, Baron chose MapQuest for Business as their new geocoding provider. According to Wilcox, "MapQuest is better and much more accurate than our previous provider." MapQuest geocodes user addresses within Baron's apps, translating even the most rural address into latitude and longitudinal coordinates, which are used in meteorological data. The end result is that users know exactly whether they or their loved ones are in the path of any significant weather system.

    Enabling 'narrowcasting' to specific users

    Chief Meteorologist Dave Freeman, with KSNW TV in Wichita, KansasIn a video on Baron's website, Chief Meteorologist Dave Freeman, with KSNW TV in Wichita, Kan., commented on the precision of the location data in Baron's application, saying that it is "highly-specific; with geofencing you are able to target the people in the path of dangerous weather conditions – and only those people. So it is very much, 'narrowcasting' critical information to just the people who need to know about it."

    A wise decision

    Wilcox is very pleased with his decision to be using our Geocoding API. "MapQuest is a good company to work with – they're very reliable and have excellent customer service. I can't ask for much more than that. I would definitely recommend MapQuest to anyone looking for similar geocoding capabilities."

  • Building innovative products in 24-hours at TechCrunch Disrupt Hackathon NYC

    Recently, Verizon Companies MapQuest, Sensity and it's ThingSpace team joined together to co-sponsor TechCrunch Disrupt's Hackathon in New York City on May 13-14, 2017.

    Nearly 700 hackers descended upon Pier 36 to create new products utilizing sponsor APIs and SDKs for the chance to win big. Teams were also given the opportunity to present to a panel of expert judges and sponsors on the TechCrunch Disrupt stage.

    While in the Big Apple, we opened up our APIs and SDKs for developers to create an advanced, finished product that successfully implemented multiple APIs. Those that rose to the challenge competed to win:

    • First Place: $3,000
    • Second Place: $1500
    • Third Place: $500

    In the end, we had 12 teams utilizing MapQuest and Sensity Smart Cities APIs. Read on to learn about the top 3 teams:

    First Place: is an application that allows users to bid on local parking spaces that are occupied by autonomous vehicles. The highest bidder is alerted of their winning spot, notified using ThingSpace APIs and sent directions using the MapQuest Directions API and our Leaflet Maps Plugin, and the autonomous vehicles then drives away to find another spot to park in.

    Second Place: IntelliDrive

    IntelliDrive is an application that offers time-based, contextual intelligence to users on road trips. The app offers suggestions, such as nearest restaurants along your route and sends alerts and suggestions related to low fuel and gas stations nearby. IntelliDrive utilized ThingSpace APIs for notification and MapQuest's Search, Icon Service, Directions and Traffic APIs, as well as our ios SDK.

    Third Place: Swerve

    Swerve is a car collision mapping and visualization tool that helps insurance agents easily view and interpret collisions. Utilizing Verizon's Sensity Smart Cities APIs along with Device Messaging APIs, Swerve visually displays where a collision occurred and icons to show which vehicle was where at the time of the incident. Serve also used MapQuest APIs for determining the location of the accident.

    Congratulations to all of the teams who participated in TechCrunch Disrupt Hackathon. Now, go get some sleep and then keep on coding!

  • Release of Icon Service V2!

    We're happy to announce the release of a new version of our icon service! This new version (V2) introduces crisp, flat and fast loading icons that look great on our Leaflet and static maps. Full documentation can be found at:

    When I first started working for MapQuest last year, we had a team prototype hack day to see what types of icons we could generate for usage in our internal maps and for the greater developer community to enjoy. We found that starting off with vector images and type, we could generate icons on the fly at any size and color that were clean and had crisp edges. This had the added benefit of working seamlessly with retina maps. This hack evolved into a platform API, and I'm happy to introduce it!

    For maps, the most popular icon is the marker, and the simplest way to retrieve one is to hit:

    Wanna change the size? It's easy, just use one of our pre-baked sizes: sm, md, lg. Want to supersize it for retina? Just throw @2x at the end of the size and get an icon at twice the resolution:

    Black markers not your thing? You can customize to colors of the marker with hex values to dial in that color that your brand needs (go Broncos!):

    That's great, but what if you want Peyton Manning's number on there? Just add it to the dash ("-") delimited values in the url:

    Markers are nice, but why should we limit ourselves to just one shape? We threw in circles, flags, vias, construction, incident and external icons into the mix to cover all of the use cases:

    Circles behave a lot like markers:

    A via is like a circle, but much smaller. Because this little icon is so....little, we don't put text in the middle:

    While vias don't say much, flags can fit up to 5 characters:!-lg.png

    When you want to show incidents and construction on your map, we have plenty of options:

    You can also pull in external icons through the service. We cache this image so you get speedy results on subsequent calls. Let's first look at the external icon api:

    We make it extremely easy. Insert your URL (doesn't have to be encoded) at the end of the base endpoint to get the feature:{EXTERNAL_URL_HERE}

    Now that you know about our icons, you can really grok the service by replacing the .png extension with .json:!-lg.json

    This returns information about the icon in JSON:


    "iconUrl": "!-lg.png",

    "iconRetinaUrl": "!-lg@2x.png",

    "iconSize": [80, 40],

    "iconAnchor": [0, 40],

    "popupAnchor": [0, -40],


    This information becomes powerful when you combine it with MapQuest's Leaflet plugin to place the icon on a Leaflet map:

    var map ='map-custom-icon', {layers: MQ.mapLayer()}).setView([51.505, -0.09], 13);

    var icon = '!-lg.json';

    $.getJSON(icon, function(json){

    var LeafIcon = L.icon(json);

    L.marker([51.509, -0.08], {icon: LeafIcon}).bindPopup("I'm a custom icon using " + icon).addTo(map);


    That's how I felt when I went pub crawling in London and got lost. I hope you're not lost or confused when working with this API. If you do get lost, check out our online documentation at or jump on our forums at and ask a question.

    In our next icon service blog post, I'll discuss how to simplify the creation of icons with the Online Icon Builder. Until then:

  • What to do when you're looking for support

    Hi, my name is Brian Coakley and I'm the leader of the developer tools support team. I've been here for over 10 years, meaning I've worked with several people to overcome their challenges. So, what do our customers frequently ask about?

    Can you help me figure this one out? Well, we sure can. We often get pulled in to help people fix data issues. Does the route to your house take you to the middle of the city? Do your search results show up in Toledo, OH instead of Toledo, WA? Most hiccups are caused by the inability to find a location. Geocoding is the science, religion and art of associating a address with it's latitude and longitude. If this process fails, everything that comes after it does too - the route, the search, the map. So let us know what address is causing a problem and we can fix it. Depending on the situation, we can typically fix this type of hurdle in a matter of a few hours.

    How can I get x functionality to work in my application? We help people learn how to use our various mapping offerings. Do you want to add a search to find your business? Are you looking to send someone a route from their house to your party? Do you need a satellite map to see what's around that new house you're dreaming of buying? Those are pretty easy. Are you looking to pinpoint the manager for a sales territory to help solve an issue of a complaining customer of yours? We teach people how to use Data Manager and our Search APIs to help turn around unhappy customers.

    What's coming next? While this blog is full of information about new products, the support team knows what's coming out next week, next month and next year. Let us know what you're trying to do and we'll help make it happen with today's tools or tomorrow's shiny new releases. If we don't have it yet, we're the ones who can take it to the teams who develop new features. If you have a good idea, let us know.

    You have a question - we've got answers. Call, email or post in the forum. We're all over those. If you tweet or StackOverflow we'll get to those too. But don't sit there and wonder what's wrong or how to do something. Let us know how we can help and we'll keep you rolling along. It's what we do.

  • Sponsoring HackCU III: The Largest Hackathon in the Rocky Mountain Region

    MapQuest loves hackathons. Whether we're sponsoring, mentoring or helping students utilize our APIs and SDKs, we love to be involved. We particularly love getting involved at a local level, helping mentor the up-and-coming tech generation, who may be sitting at a desk next to us one day!

    On April 22-23, 2017, we sponsored HackCU III, the largest hackathon in the Rocky Mountain region. More than 400 students, from all over the country, descended upon University of Colorado–Boulder to express their creativity, ingenuity and determination to create anything their hearts desired.

    MapQuest opened up our APIs, SDKs, and our new spatial intelligence platform, We also handed out a ton of great swag and sponsored a grand prize for the top team who utilized our products in the most innovative way – Ultimate Ears bluetooth & waterproof speakers for all.

    Out of six teams using MapQuest, we could only choose one winner. That team was ...

    OBD Buddy

    Expanding navigation application capabilities, OBD Buddy paired on board diagnostics data from a vehicle with MapQuest's Directions and Search APIs. The end result provided drivers and riders with contextual information and suggestions based on their location and car data.

    For example, a user is on a road trip and realizes that they are running low on fuel. Because the application knows their destination, and how much fuel they have left, OBD Buddy quickly warns them and suggests the nearest gas stations. From there, the user has the opportunity to add the nearest station as a way point, and be redirected for a refuel.

    Congratulations to all the teams who participated in HackCU III. Read more about OBD Buddy's project here and be sure to sign up for a free developer account to access our location-based APIs and SDKs.
